Summaries for TNPO3 Gene

Entrez Gene Summary for TNPO3 Gene

  • The protein encoded by this gene is a nuclear import receptor for serine/arginine-rich (SR) proteins such as the splicing factors SFRS1 and SFRS2. The encoded protein has also been shown to be involved in HIV-1 infection, apparently through interaction with the HIV-1 capsid protein. Two transcript variants encoding different isoforms as well as a noncoding transcript have been found for this gene.[provided by RefSeq, Jul 2010]

GeneCards Summary for TNPO3 Gene

TNPO3 (Transportin 3) is a Protein Coding gene. Diseases associated with TNPO3 include muscular dystrophy, limb-girdle, type 1f and autosomal dominant limb-girdle muscular dystrophy type 1f. GO annotations related to this gene include receptor activity. An important paralog of this gene is IPO13.

UniProtKB/Swiss-Prot for TNPO3 Gene

  • Seems to function in nuclear protein import as nuclear transport receptor. In vitro, mediates the nuclear import of splicing factor SR proteins RBM4, SFRS1 and SFRS2, by recognizing phosphorylated RS domains.

Disorders for TNPO3 Gene


  • Limb-girdle muscular dystrophy 1F (LGMD1F) [MIM:608423]: An autosomal dominant myopathy characterized by proximal muscle weakness primarily affecting the lower limbs, but also affecting the upper limbs in most patients. Affected individuals also have distal muscle weakness of the hands and lower leg muscles. The disease has generally a benign clinical course but some individuals with childhood or juvenile onset manifest severe widespread myopathy, leading to wheelchair dependency and respiratory insufficiency. Muscle biopsy shows dystrophic changes with abnormal nuclei, rimmed vacuoles, and filamentous inclusions. {ECO:0000269 PubMed:23667635}. Note=The disease is caused by mutations affecting the gene represented in this entry.
